Dealer W Love All IMPs
A deal from the Spring Fours held recently. Four notrump was a quantitative slam try.
Superficially, looking at the hands above you might want to play six notrump. If the hearts break 4-3 (62%) you will have three spade, five heart, two diamond and two club tricks for a total of twelve, if the hearts don't break there are also a few squeeze chances. However, looking at it more closely there are entry problems. For example, on a diamond lead, you win in dummy, play a heart to the queen, then a club to the king and run the hearts. But then if the defence can hold up the spade ace for two rounds you can't get all your black suit tricks. In general singleton honours are not worth their full point count value and should be devalued.
Ncholas Greer and Phil Taylor did well to avoid this slam (especially as the hearts broke 6-1).
Thanks to Nicholas Greer for this deal
